FINING COMPOSITlON.

YJPECEFICATION forming part of Letters Patent No. 341,239,6ated May 4, 1886.

Application filed February 20, 1886. Serial No. 199,661.

To aZZ whom it may concern:

Be it known that l, Monrrz HERZOG, of Hoboken, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Filling Compositions, of which the following is a specification.

Thisinvention relates to an improved fining composition to be used as a substitute for all kinds of isinglass in the lining of beer, ale, cider, wine, and other fermented liquids; and the invention consists of a fining composition formed of a mixture of pulverized salep and a suitable acid.

In preparing my improved fining composition the roots of salep (Orchis mascula, Orcluis flforio, Orchi's militm'is Linn.) are pulverized and one hundred parts in weight of the same mixed with from two to six per cent. in weight of a suitable acidsuch as tartaric acid, salicylic acid, bcnzoic acid, phosphoric acid, 850. I. prefer to use salieyli c acid, as thereby the fermented liquids are also preserved for a certain length of time. The mixture of pulverized salep and acid is dissolved in hot water, the acid facilitating and accelerating the solution of the salep in water. The fining solution is then added to the liquid to be fined. The albuminous and glutinous substances in the same are then precipitated in the usual manner by adding from two to ten per cent. in weight of tannic acid to the liquid.

The advantage of my improved fining com- (No specimens.)

position as compared to the different kinds of isinglass heretofore in use consists, mainly, in the quick and easy solution of the fining composition in hot water, and, secondly, of the quick fining action by the glutinous ingredients contained in the salep and the quick settling of the albuminons and glutinous substance by the action of the tannic acid, while a preservative influence is exerted on the liquid when benzoie or salicylic acid has been used in preparing the fining composition.

I am aware that linings composed of isinglass, sulphurous acid, and water, also a iining composition consisting of a mixture of gelatine prepared from skins and salicylic acid have been used heretofore, and I lay no claim to the same.

Having thusdescribed my invention, Iclaim as new and desire to secure by Letters Patent 1. A fining composition consisting of a mix ture of pulverized salep and a suitable acid, substantially as set forth.

2. A fining composition consisling of a. mixture of pulverized salep and a preservative acid, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.

MORITZ HER-ZOG.
